On October 2, 2025, the India Meteorological Department (IMD) slapped a yellow rain alert on Delhi-NCR, Uttar Pradesh and Bihar, just as the city gears up for Dussehra and the tail‑end of Durga Puja. The warning isn’t a vague heads‑up; it comes after a heavy downpour on the morning of October 1 that sent gusts up to 50 km/h and left the capital’s streets puddled, traffic snarled and residents both relieved and frustrated.
Background: Monsoon Retreat and Post‑Monsoon Showers
India’s monsoon officially pulled back on September 30, but the atmospheric lull is anything but silent. Historically, the first week of October sees lingering convective activity across northern India, especially when the western disturbances clash with residual moisture. This year, the clash happened squarely over the Indo‑Gangetic plains, prompting IMD forecasters to issue a series of alerts.
According to Naresh Kumar, senior scientist at the IMD, “light to moderate rain was on the radar for the past few days. The wet spell we’re seeing now is a classic post‑monsoon pulse that often eases the lingering humidity but can still splash major events.”
Day‑by‑Day Forecast Details
The IMD’s 1330 hrs IST bulletin on October 1 recorded a 3‑5 °C dip in minimum temperatures and a 1‑3 °C dip in maximums across Delhi‑NCR. On the ground, that meant a high of 32‑34 °C and a low of 22‑24 °C – a welcome break from the scorching pre‑monsoon highs.
- October 2: Generally cloudy with very light to light rain, thunderstorms in the afternoon, max 33‑35 °C, min 24‑26 °C, 64 % chance of rain.
- October 3: Partly cloudy, max 34 °C, min 25 °C, isolated thunderstorms with a 47 % probability.
- October 4‑5: Mostly sunny, late‑day showers possible, max 35 °C, min 24‑25 °C.
- October 6: Dark clouds may return, heavy rain threatened in the evening.
Wind patterns are also shifting. The morning of October 2 saw a gentle northeast breeze under 10 km/h, but by afternoon a southeast flow picked up, gusting to 30 km/h.
Impact on Dussehra and Durga Puja Celebrations
Dussehra is slated for October 2‑5 across the capital, with large processions, fireworks and community feasts. The IMD’s yellow alert means organizers are bracing for intermittent showers that could dampen open‑air stages. Likewise, Durga Puja – still in its final days – faces potential disruptions, especially for the evening “Sandhya” rituals that rely on clear skies for lighting and music.
Local municipal bodies have already issued advisories: avoid low‑lying routes, keep drainage clear, and consider postponing marquee performances by a few hours if thunderstorms roll in. Residents, on the other hand, are making do with waterproof covers for idols and setting up temporary shelters in community halls.
Regional Outlook: Beyond Delhi‑NCR
The rain isn’t confined to the capital. The IMD’s extended outlook highlights heavy showers in eastern states – isolated spots in Odisha, Bihar and Vidarbha saw measurable rain on September 25‑28. Northeast states like Nagaland, Manipur and Mizoram are also under a cloud‑burst watch, though the intensity is expected to be lighter.
Temperature-wise, most of the country will stay near or below normal for the first week of October. The highest peak will be 39 °C in Madurai, Tamil Nadu – a reminder that while the north cools, the south still wrestles with heat.
Expert Opinions and What It Means for Daily Life
Climate analyst Dr. Ananya Singh from the Indian Institute of Tropical Meteorology notes, “Post‑monsoon rain is a double‑edged sword. It cuts down humidity, which is a relief for asthmatics and those with heat‑related ailments, but the sudden downpours can flood poorly drained urban pockets, especially in older parts of Delhi.”
Local businesses are already feeling the ripple effect. Street vendors near Connaught Place reported a 20 % dip in foot traffic on October 1, while some restaurants have moved indoor seating to avoid soggy courtyards.
What’s Next? Monitoring and Preparedness
The IMD says it will continue to issue hourly updates through October 6, with a particular focus on thunderstorm intensity and potential flash‑flood zones. Citizens are urged to keep smartphones charged for alerts, and to heed any evacuation notices from the Delhi Police.
In the meantime, the city’s festival committees are tweaking schedules. The grand Ramlila performance on October 3 will start an hour later, hoping the afternoon cloud cover will have lifted. Fireworks for Dussehra are being shifted to the night of October 4, when the forecast shows a slight dip in thunderstorm probability.

Frequently Asked Questions
How will the rain affect Dussehra celebrations in Delhi?
Organisers expect intermittent showers, so many outdoor stages will shift to later in the evening or move indoors. Fireworks are being rescheduled to October 4 to avoid the peak thunderstorm window. Residents are advised to carry umbrellas and stay clear of low‑lying areas where water‑logging could occur.
What areas in Delhi are most prone to water‑logging during the forecasted rain?
Old Delhi’s narrow lanes, especially around Chandni Chowk, and the South Delhi districts near the Ring Road have historically struggled with drainage. The IMD advises residents in these zones to keep sandbags ready and monitor local ward alerts for any sudden rise in water levels.
Will the post‑monsoon rain bring any health benefits?
Yes. The drop in humidity (down 5‑7 % on average) can ease respiratory discomfort for asthmatics and lower the risk of heat‑related ailments. However, standing water can become a breeding ground for mosquitoes, so preventive measures remain essential.
What is the likelihood of a heavier rain spell on October 6?
The IMD’s outlook shows a 40‑50 % chance of a moderate to heavy downpour on October 6, especially after dark. Authorities are keeping a close eye on the western disturbance that could deepen, potentially causing localized flooding in low‑lying districts of Uttar Pradesh and Bihar.
How can commuters best navigate the traffic disruptions?
Plan for extra travel time, use Metro wherever possible, and avoid routes near the Yamuna’s flood‑prone embankments. Real‑time traffic apps are updating routes dynamically, so keeping your phone’s GPS on can help you sidestep bottlenecks.
